Biorthogonal-only Floquet Dynamical Quantum Phase Transitions
Jiangrong Wen, Qidong Yuan, Zi-Xiang Hu +1
Non-Hermitian dynamical quantum phase transitions (DQPTs) are intrinsically sensitive to the choice of inner product under nonunitary time evolution. Although the biorthogonal form…

Biorthogonal Dynamical Quantum Phase Transitions in Non-Hermitian Systems
Yecheng Jing, Jian-Jun Dong, Yu-Yu Zhang +1
By utilizing biorthogonal bases, we develop a comprehensive framework for studying biorthogonal dynamical quantum phase transitions in non-Hermitian systems. With the help of the p…
